Antirattle device



Feb. 27, 1934. I. ANDREWS ANTIRATTLE DEVICE Filed June 2, 1932 awe/whom Jszzae flrzdfiews Patented F eb. 27, 1934 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to an anti-friction bearing for use as an anti-rattling device and for other purposes and which can be used in connection with motor vehicle doors, and aims to improve generally the construction as shown and described in my Patent Number 1,813,132, dated July 7, 1931.

An important object of the invention is the provision of means which will not only restrict movement of the door with respect to the vehicle body to eliminate rattling of the door, but one which will act to urge the door to its open position when the door latch is operated to release the door.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a fragmental elevational view illustrating an anti-rattle device constructed in accordance with the invention.

Figure 2 is a vertical sectional view through the upper section of the anti-rattling device.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure 4 is a sectional view taken on line 44 of Figure 3.

Referring to the drawing in detail, the reference character 5 designates a door jamb, which is formed with a cut out portion 6, in which the keeper section of the anti-rattle device is secured.

The keeper section embodies a plate '7, which is formed with laterally extended parallel flanges 8 extending from opposite side edges thereof, the parallel flanges 8 being arranged in pairs, the pairs being spaced apart providing a clearance for the tongue 9 of the anti-rattling device, to be hereinafter more fully described.

As clearly shown by Figure 2 of the drawing, the upper and lower edge of the flanges 8, are formed with inwardly extended flanges 10. 50 Certain of the flanges 10 provide stops for the plates 11, which plates provide supports for the blocks 12 of rubber material, which blocks support the ball races 13. These ball races 13 are formed with grooves in which the balls 14 are positioned, the balls 14 being held in position by means of the caps 15, which are formed with elongated openings through which the balls 14 project, so that they may contact with the finger 9, when the door closes.

Laterally extended flanges 16 are formed on the caps 15, and cooperate with inwardly extended flanges 1'7 formed on the parallel flanges 8, thereby providing means whereby the caps 15 will be securely held in position, and permitted to slide against the action of the rubber blocks 12, when pressure is exerted thereon.

As clearly shown by Figure 2 of the drawing, these caps are constructed in such a way that the outer surfaces thereof are inclined providing a tapered opening for the reception of the finger 9.

It will also be seen that the ball races 13 are constructed to provide inclined surfaces over which the balls 14 move.

In view of the fact that the tongue 9 is formed with inclined upper and lower edges to cooperate with the balls supported within the keeper section of the anti-rattler, it will be seen that a wedging action is set up between the tongue 9 and balls of the anti-rattler, and the balls 14 will be placed under pressure, as the balls are forced rearwardly within the ball races.

It follows that when the latch of the door is operated to release the door, the outward pressure exerted on the upper and lower surfaces of the tongue 9, will act to urge the door to its open position.

The reference character 18 designates a cover plate which is of a length to extend over the entire keeper section of the anti-rattler, the cover plate acting to hold the elements of the keeper section in position at all times.

Importance is attached to the provision of slots in the caps 15. The balls 14 project into these slots and are normally braced firmly against the walls thereof by the cushioning means. Thus these balls cannot roll freely. However when the tongue 9 is moved into position it will engage the balls and depress them away from the walls of the slots, so that, as the tongue continues its movement, the balls can roll freely and without friction within the slots. When the tongue is withdrawn it will roll the balls back to their initial positions where they will again be clamped in place by the cushions, if the tongue leaves them.

I claim:

1. An anti-rattling device for doors, comprising a keeper section secured to the door jamb, upper and lower ball races mounted within the keeper section, and having inclined surfaces, balls operating over the inclined surfaces, a Wedgeshaped tongue carried by the door and adapted to move between the ball races, exerting pressure on the balls and ball races, and yieldable means within the keeper section for normally urging the balls outwardly.

2. An anti-rattling device for doors comprising a keeper member secured to the door jamb and having inclined surfaces, anti-friction members on the inclined surfaces, a tapered finger secured to the door and adapted to move into the keeper member between the anti-friction members and said anti-friction members exerting a pressure on the inclined surfaces of the finger to urge the door outwardly.

3. An anti-rattling device for doors comprising a keeper member secured to the door jamb, movable ball races mounted within the keeper, balls mounted in the ball races and arranged in pairs, the ball races presenting inclined surfaces, a tapered tongue carried by the door,.said tongue adapted to move between the ball races of the keeper, and yieldable means exerting a pressure on the balls for urging the balls into engagement with the tongue, said balls exerting a pressure on the tongue urging the tongue from the keeper.

4. An anti-friction device of the class described, comprising a keeper having a tapered recess provided with slotted walls, anti-friction devices seated in the slots and projecting into the recess, cushioning means exerting constant thrust against said devices to bind them against the walls of the slots to hold them against free rolling movement, and a member insertable into the recess to depress the anti-friction devices thereby to disengage them from the walls of the slots, and roll them along the slots.

5. An anti-friction device of the class described comprising a member having a slot, an anti-friction device projecting through the slot, a cushioning means for normally binding said device against the member to hold the device against free rolling movement in the slot, and

means for sliding engagement with said antifriction device to depress it from engagement with said member, and roll it longitudinally of the slot.

6. "In a door dovetail, in combination, a casing, an abutment thereon, a carrier vertically slidable in saidcasing above said abutment, a substantially non-resilent roller carried bysaid carrier and exposed below the same, said carrier having an inclined surface over which the roller moves and resilient means for urging said carrier downwardly.
